Water. You come back.
— Donna to Ryn[src]

Donna is a main character on Freeform's series, Siren. She is portrayed by Sibongile Mlambo.

Donna is a mystifying, deceptively powerful mermaid and Siren. When she and her sister, Ryn, were out swimming, Donna was captured by fishermen, separating her from Ryn. When captured, she attacked one of the fishermen on board, before being taken by the military on a helicopter to their military base. The scientists began to experiment on her. While in her tank, she studied the doctors and scientists. One day, she attacked and killed many of the employees at the military base, allowing her to make her escape. She has since reunited with Ryn.

She took the name of Donna when she escaped from the government facility where she was being held, and killed a nurse named Donna for her clothes and ID badge.

Donna being held in a fish tank

Donna and her sister Ryn were swimming in the ocean when Donna was captured by a group of fisherman, Xander McClure, Sean McClure and Chris Mueller and Calvin. However, her entrapment was unintentional and they had no idea that she was a mermaid upon her capture. When Chris came at her with an axe, she attacked, severely wounding Chris before running for cover. She remained hidden until a Navy SEAL team arrived and hauled her away in a steel chamber after shooting her with tranquilizing darts.
